To all whom it'may concern;

"cAnoLUs'E, DAILEY, or ma a-aw Be it known that -I, CimoL s E; DA I LEY a citizengof' 'the United States of America,- rev siding in the borough of Brooklyn, county of Kings, and State of New York, have invented certain new. and usefullmprovements in Machines for Decorticating Manila Fiber and LikeSubstances, of which the following is a specification. v

My invention. relates to machines for decorticatlng manila fiber and other fibrous material where it is, necessary to remove the pulp and outer skin from the leaves or bark to obtain the fibrous material, which is specially used in the manufacture; of cordage, twine,&c.

' My invention has for its object to furnish a light, compact, and convenient machine which may be easily carried about from one place to another and which will be-simple and effective in thoroughly crushing, scraping,

and cleaning the leaves at. one operation, leaving the fibrous material. clean and straight ready for baling. I

In th a'ccompanying drawings, Figure 1 is I a plan view of amachine embodying my in "vention, with art's thereof shown broken I away. Fig.2 1s a side elevation of my ma chine. Fig. 3 isa sectional elevation on the line 3 3, Fig. 2, and Fig. 4 is a detail view of the clutch-pins. e

I I -Referring to. the drawings, A A" represent ftwojaws secured to blocks on the bars .13 B,

' mental gears D D, which. are

. 4.0 v i each'sideof the 'aws, is a similar lever G", the

mounted in bearings in uprights C on the framing of the machine. These ba'rslB B are turned by -means of intermeshing 'seg operated by pressureon the foot-lever E through the con 'necting-rod F and the lever Gr, also connected :;to the bar B. Onathe upper bar B on' v endof which is connectedto the'lever G by means of a spring H, adapted to tend to keepy connected the jaws together, with a certain amount of -45 .ressure. This pressure mairbe' regulated means'of a nut-h on the t 'eaded rod h, y with the' end 'of the spring. --It ll-be noted that the jaws may be made of suitable (material "havin sufficient strength, yet, thinand light in v hight. .The knife-edges rat the ends of the jaws are pref elwbly made of steel and securedto the jaws by screws orother ,suitable means. The

knifes' edges extend ina substantially straight lineacross the machine, -but are set at an an- Specification of LettersPatentL kfat' eiited Maire 7 application fiiea-se temterzn'eoa.'s r nnaz'raseeg';

"Mounted on the frame in suitable.-

C C are two sets of fluted rollers'l 1 and l 1 extending acros's'and front of "the jaws, so that they are adapted to 'pull theleaves and fiber throughb etween the knife-edges. These rollers are operated from themain drivingare heldin contact vvitlrthelower rollersby the springs regulated byjthe threaded'bolts 7c".-

The maindrivi g shai'tl t 'jbjet rnedi byhand or may be power 'driven,}both means being shown-in Fig. 1.."1 The crankj Jiat' the' left in Fig. 1), is providedlwith.an' iter ear J which meshes with-a stationary gear 1 surrounding the shaft I and securedt'o the frame,

and also with similar gear J secured tothe end of the shaft, so that two revolutions of,

the shaft are obtainedfor the single rotation of the handle. When-it is dcsired'to '1 power mechanism at theoth end ,thr

communicatedl'rom a sprocl ieewheel to "the shaft throuh the .clutchM, which is keyed thereto. This clutch may be of any wellknown simple and quick-acting form, such as a pin-clutch, as shown, which consists of proj ectin pins 'm m from the sprocket-wheel and c utch that engage each other when thrown into gear. This clutch'M is for the purpose of'stopping-the rollers quickly onmentioned; This rod .30 passes through a. block N on an arm 0 on e,sheft O, which is sprockehvvheel. There is also keyed to the.

opem'n the jaws when a new leaf is about to be inse ted. The conical portion m of the clittch acts as s friction-brake and engages a, corresponding concave member M, secured to the frame, so that when the clutch is released from the sprocketcvheel by mechztnism hereinafter described it engages this stetionary part and instantly stops the rollers. The clutch is operated or thrown in and out of gear by means connected with the foot-1cver E for opening the jaws. This footlever, which is pivoted to the frame, as at is 0011- nected to the lever G by the rod F, as before mounted in suitable bearings o 0 in the frame. At the opposite end of this shaft 0 is enoth or arm as shown by dotted lines in Fig. 2 end by, full lines in Fig. 3. From. this arm 0 extends av connecting-rod connected to a collar P, edjustebly secured by a. set nnt p on the rod P, which is connected to the lever M to throw the clutch in and out of gear. Above the arm 0 is an adjustable collar N on the rod F to engage the block N on the arm 0, as the'rod F moves downward. The amount of motion therefore necessary to operate the clutch may be re listed by shiftin this collar N up or down. letween the collar P and the side of the frame I prefer to provide about the shaft a coiled spring P, which tends to hold the clutch in engagement with the main driving-sheft I a suitable flywheel R.

The operation is as follows: When it leaf is to be inserted in the machine, the foot-lever E is pressed down to open the jaws, and the leaf is pressed met the rear end over the central bar A and between the open jaws until o it comes in contact with the'fiuted rollers.

Tl1en "'when the pressure is released on the foot-lever the jaws imm'edietel close .011- the leaf, owing to the action of t e springs H. On the closing of the jaws the rodl goes up, and through the release of the bell-crank l'eyer the connecting-rod 0 moves the rod P horizontally, so as to throw the clutch into gear with the sprocket-Wheel. The feedrollers are thereby started and pull the leaf through between. the knife edges and pass, it

down over-a delivery-apron S. After the leaf has passed entirely through the rollers the foot-lever .is a sin pressed to throw out theolutch and app y the friction-brake, sto

pingthe rollers almost instantly, and by t e same action of the foot-lover the two jaws are both. separated from each other, so that both jaws may olesr themselves from the pulp.

I claim as my invention- 1. A machine for dccorticating mm'iile fiber mid the like, comprising movable jaws, means for openhig and closing said jaws,

knives carried. by the jaws, rollers for drmw ing the fiber between the knives, and means for simultaneously opening the jaws and stopping the rollers.
